Geographic Range [top]

Range Description:	Turnix worcesteri is endemic to the island of Luzon in the Philippines, where it is known from just six localities. Virtually all records have derived from bird-catchers and are assumed to be intra-island migrants. There is a recent (January 2009) record of an individual caught and photographed at Dalton Pass (Allen 2009). The limited available evidence suggests that it breeds somewhere in northern Luzon in April-June and that at least some birds disperse southwards in the period July-March. Thus its true range (and habitat) remain obscure. It appears to be rare; however, buttonquails are a notoriously cryptic and unobtrusive family of birds, and the species could conceivably occur in reasonable numbers somewhere. If it does inhabit grasslands, it cannot be assumed that increases in this habitat on Luzon have benefited the species, which may prove to have specific ecological requirements not met by the creation of pastures or cropland through forest clearance.

Population [top]

Population:	The population size of this species has not been quantified, although it has been described as rare.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	It may be confined to grasslands in the highlands of the Cordillera Central, although records are from 150-1,250 m, and the possibility that it frequents forested (non-grassland) habitats cannot be discounted. It has been stated that it inhabits tall grass under pine trees (per Allen 2009), although this requires verification.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	Hunting evidently poses a threat (e.g. at the migratory funnel and bird-catching area of Dalton Pass, Nueva Vizcaya), but the impact of this on its population cannot currently be gauged.
